Specieaton of Letters Patent.

Patented March 3, 1908.

Application filed November l5. 1905. Serial No. 287.458.

To all 1/:71 om it 11mg/ concern.'

Be it known that l', Proto liesse, a resident of Pittsburg, in the county of Allegheny and State elf Pennsylvania, have invented a new and useful lniproveinent in Envelops, and I do hereby dechire the following to be a full, clear, and exact description' thereof.

My invention relates to envelops and has especial reference to safety envelops dcsigned for use by express companies, banks, trust companies, etc.

The object oi iny invention is to provide a cheap, simple, and ellieient forni ol envelop, v

practically impossible to open after sealing 'without inarring, tearing, or destroying the same, as well es one which can be easily handled and sealed by any unskilled person.

In the drawing, Figure l is a-plnn view or elevation ol the blank for forming my ilnproved envelop. Fig, 2 is a like view, showing the end flaps connected together.' Fig. 3 is a like View showing the saine l'olded in its completed forni. Fig. l is an enlarged ysection on the line 4**1 ol Fig. 2. Fig. 5 is a likey view on the line .f5-5 ol Fig. 3.

Like S \.r1nbol.s oll reference indicate like parts in each ligure.

illustrated, l is the blank provided with the inflin or address portion 2, frein which extend the end 'llaps 2S, 3', each having a slit 3" therein, providing portions 3" and 3b, the portion 3a on the left-hand side of the drawingr being gunnned on its inner' side alongside the opening or slit, as shown at 4" in full lines, and the portion 3u on the righthand side of the drawing being gunnned on its inner side as shown at 4'. rlhe lower portion of the end ilap at the lelt hand side of the drawing has no geni or sealing niaterial applied to either face, .but the lower portion 3b on theyight hand side is guinnied on its inner side along the outer edge, as Well as a tongue 4 which extends outwardly there# frorn. Connected to the inner' side of the iiap 3' at the inner edge thereof, by the gurnined surface 5', is the inner sealing flap 5, which extends beyond the outer edge of said flap 3', as at 5". Extending l'roin one side of the mein flap 2, is the rear sealing flap 6, which is gunnned et 6' along the inside of each of its ends, and is provided with the three longitudinal cuts or slits 7", Aforming two strips 7, 7', the strip 7 being;r gunnned on the inside as'at 7a. Extending from the Gtherside of the 11min flap 2, is the main sealing flap 8,'Wl1ieh is provided with the curved end edges 8', leading from said front and terminating in the tongue portion 9. This llap' S is gunnned Ion the outside as shown by dotted lines at 8"', and the tongue thereon is gunnned on the inside as shown by full lines at 9'.

To forni the blank into an envelop after the inner' lla p 5 has been secured to the end flap y3', as above described, and shown iii-Fig.

1, the llap 3 with said flap 5 is folded over on the dotted line e. Then the other end llap 3 is folded over on the other dotted line a., the two parts of the llap being inserted between the llaps 5 :1nd 3'. The guinined surl'ace 4" will cause the portion 3 of the llap 3 to adhere to the ilztp 5, and the gunnned sur.- lace 4' of the portion 3f* oll the [lap will canse it to adhere to the outer side of the other portion 3. Then the tongue 4 is in serted in the slot 4 and turned backwards, its gunnned sui-'luce causing it to adhere to the inner side 3l) ol' the llnp 3b, while the guinmed surl'ztcc It' ol the portion 3b ol.t the lla) 3' will cause it to adhere to the outer side o the other portion 3b. The portions 3 ol the two llaps are thus securely held to the lap 5 and to each other, and the portions 3b securely held together, but not to the ilap 5, thus lorining an opening orpocket between the llap 5 and the portions 3b of the ilaps 3, 3',

into which leads an opening B. rlhe rear sealing ilap 6 is then bent and folded over the end flaps 3, 3', on the dotted line b, and sealed to said end Haps by the guinnied surfaces 6' at their edges and by the gunnned surface 7a on the strip 7' on said iiap engaging with the portions 3EL on the end flaps 3, 3',

My improved envelop is now ready for use. The material to be carried therein is placed within the space or pocket C lorrned between the iront 2 and inner llap 5, after which the C niain sealing ilap 8 is bent or folded over on to the flap on the dotted line c, and the envelop is sealed by inserting the tongue 9 ol".

the llap Sunder the strip 7' and through the opening B into the space between the por.- tions 3b of the end flaps 3, 3', and the flap 5.

The Ouinneed surface 9 on the tendue 9 ofthe iap 8 is then sealed to the ilap 5 and the guinined surface 8 on the opposite side of said flap sealed to the under facel of the strip 7 on the Hap 6.

lt will thus be seen that my improved envelop when ready for use and sealed Will prevent any tampering or removing of its contentsiwithout tearing or inarring some part of the same, and in the event of any tamperin Y it would be impossible to restore the enve op to its origina condition.

Various ino iiications and changes in the design and construction of In improved envelop may be resorted to wit out 'departing from the spirit of. the invention or sacrificing .in the rear flap.

y 2g. An enve op comprising a front or address side, end flaps, an inner fla secured along the inner portion of one of sai end fiaps, each of said end ilaps having a slit therein dividing each iap into two portions, the upper portions being sealed to each other and also sealed to said inner Hap, and the lower portions sealed to each other but not to the inner ap,forming a pocket between said lower portions and said inner flap, and a main sealing ap extending through said slit in the reara into said pocket and adapted to be sealed t erein. f v v secured to t 'e same, an inner-sea secured to the insidel of one ofv'said envelop comprising a front, .end-

flaps secured together and having a slit or openir'i vformed therein, an innersealing flap secure to the inside of one of said end flaps, a rear sealing flap havin slits therein to form two strips on said rear ap, and a main sealing flap for fitting under one of rsaid strips, over the other one of the same andthrough the said opening to be sealed .or secured to said inner flap vand to one ofv said strips;

4. A.n envelop com rising a front, end

beyond the opening therein, aigre flap havin slits therein to form two s Q said rear ap, and a main sea'lingilay fforit-l ting under'l one of said stri s', over t @other one of the same and throng the said opening between the lower portions of saidend'ila'psr and said inner iap to be'sealed jorfseoured to' said inner iap and to one of saidfstri s.

In testimony whereof, I the said'lAoLO l RUSSO have hereunto set my hand.
